What does optical flow do in CapCut
CapCut introduced a game-changing feature that has helped video editors effortlessly apply cinematic, smooth motion to their footage. Here are a few of the benefits of optical flow in your video projects:
- Creates smoother slow-motion: Optical flow generates in-between frames to give you a smooth time-stretch look even with slow footage. It is great for sports, floating, and action scenes that require a slow-motion appearance.
- Enhances motion transitions: If your video has multiple scenes or switching, optical flow can greatly improve the transition between them. It looks between frames, excelling at interpolating new frames, creating/smoothing out/the path of movement.
- Improves frame interpolation: Optical flow is used to create extra frames that sit in between existing ones, making the frame rate of the video smoother. You can have smoother motion (like shooting 30fps), better slowmo quality, and your video will just look better and more professional.
- Supports AI-driven video editing: A special feature of CapCut's optical flow technology is that it integrates with AI-based video editing. Motion, frame rates and transitions are dynamically synthesized, taking the hard work out of the editing process while guaranteeing a professional result every time.
How to use optical flow in CapCut for seamless motion effects
Optical flow in CapCut desktop is a powerful feature that helps create smooth, cinematic transitions by generating in-between frames for slow-motion and frame interpolation.

Open CapCut and drag your clip onto the timeline. Make sure it's a high-frame-rate or action-rich video for best results.
- STEP 2
- Enable optical flow from the video tab
Click on the video track in the timeline. In the top-right editing panel, switch to the "Video" tab. Scroll down to the "Basic" section and enable the "Optical flow" option. This activates frame interpolation, and you'll see a smoother preview of your video. You can select different frame rates, including 30 fps, 50 fps, and 60 fps.
- STEP 3
- Export with optical flow enabled
Once you're done editing, click the "Export" button at the top right. In the export settings panel, make sure your resolution, bitrate, codec, format, and frame rate are set as desired. Finally, hit the "Export" button again to save your smoothly enhanced video.
Optical flow not working in CapCut: Here's how to fix it
If optical flow isn't working in CapCut, it's usually due to common settings or software issues. Here's how to fix it:
- Ensure video speed is adjusted: Optical flow requires a slowed-down video to work. If the speed remains unchanged, the feature won't activate.
- Enable optical flow manually: After adjusting the video speed, navigate to the speed settings and toggle on "Optical flow" for frame interpolation.
- Check if you're using CapCut desktop: Optical flow is only available in CapCut's desktop version. Ensure you're not using the mobile or web versions, which lack this feature.
- Update CapCut to the latest version: Older CapCut versions may not support optical flow or could have bugs. Always update to the latest version for the best results.
- Avoid unsupported formats or resolutions: Low-resolution or incompatible formats may prevent optical flow from applying. Always use high-quality video files to get smooth results.
When shouldn't you use optical flow
- When slowing down fast-moving scenes: Optical flow can introduce warping artifacts in action-packed clips, like sports or explosions, due to rapid motion.
- With heavily compressed or low-quality footage: Artifacts and noise can confuse motion tracking, resulting in glitchy or distorted frames.
- When the subject or background changes abruptly: Sudden cuts, flashes, or scene changes can disrupt the smooth interpolation that optical flow tries to generate.
- For videos with transparent overlays or text: Text, logos, or semi-transparent layers may stretch or distort when optical flow is applied.
- In clips with camera shake or jitter: Handheld or shaky footage can confuse motion estimation, leading to unnatural smoothing or ghosting effects.

FAQs
- 1
- Does optical flow affect video quality?
Optical flow is responsible for making the video look better by producing intermediate frames, which results in better motion, no stutter, and less ghosting for slow-motion effects. But according to the quality and resolution of your video, it may cause minor artifacts if used too much. Optical flow is an excellent feature in CapCut that optimizes video while minimizing degradation.
- 2
- Can I use optical flow in slow-motion edits only?
No, it can also be applied to improve frame interpolation in videos at different speeds. Commonly associated with slow-motion video, optical flow can also help to work out any jerkiness in one clip to the next or in the overall video. For nuanced speed adjustments and beautiful playback, CapCut's optical flow updates motion in any video effortlessly.
- 3
- What's the difference between frame blending and optical flow?
Frame blending simply crossfades adjacent frames without analyzing motion, which can result in blurry or ghosting effects. Optical flow generates new intermediate frames by analyzing pixel movement, producing smoother and more natural motion, making it ideal for high-quality slow-motion effects. No matter if you want to do frame blending or optical flow for videos, CapCut meets your needs.
